Abstract

The device uses vaporisable coolant circulated via a hose (13) with a capillary pipe (14) located inside it. The device also has a contact member (1), with a partially cylindrical seat (2) for the pipe (3,5) or for an extension piece (4) and expansion chambers (6) for vaporisation of the coolant. The hose (13) is connected to the contact member (1) normal to a generating line of the seat (2) and to one side of it. The contact member (1) has an extension (16), in which a thermally insulated clamping spindle (17) is mounted to fasten the contact member (1) to the pipe (3,5). The clamping spindle contains a temperature sensor (20,20a).
